Removal & Installation

If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.

If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor.

If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.

Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure.

Install a new suction accumulator as directed by the A/C flushing or filtering procedure.

NOTE

Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

Remove the radiator upper sight shield.

If flushing of the air conditioning system has not been performed, recover the refrigerant, as outlined in this section.

Remove the drive belt from the A/C clutch pulley.

Raise and safely support the vehicle.

Remove the radiator air deflector, as follows:

Remove the pin-type retainers.

Remove the screws and remove the radiator air deflector.

Disconnect the electrical connector from the A/C pressure transducer.

Loosen the bolt and remove the A/C manifold and tube.

Disconnect the electrical connector.

Remove the bolts and the A/C compressor.

To install:

Installation is the reverse of the removal procedure. Observe the following tightening specifications:

A/C compressor mounting bolts: 15-22 ft. lbs. (20-30 Nm).

A/C manifold and tube: 14-17 ft. lbs. (18-24 Nm).

If filtering of the refrigerant system is not to be performed, lubricate the new A/C compressor with the correct amount of PAG Refrigerant Compressor Oil (R134a Systems) or equivalent.
